Description

Die Erfindung bezieht sich auf einen Stützkörper der im Oberbegriff des Patentanspruchs 1 beschriebenen, aus der DE-AS 20 50 917 bekannten Art.The invention relates to a support body in the The preamble of claim 1 described from DE-AS 20 50 917 known type.

Bei dem bekannten Stützkörper ist zur Ausbildung der Ab­ leitkanäle zwischen die porösen Platten ein Drahtgitter eingelegt, so daß die durch die Membranen hindurchgetre­ tene Gemischkomponente abströmen kann. Infolge des Draht­ gitters treten jedoch bei Erzeugung eines Druckgefälles Biegungen auf, durch die in den Membranen Falten oder Haarrisse auftreten können. Hierdurch wird die Wirksam­ keit der Trennung verschlechtert und die Lebensdauer der mit einem bekannten Stützkörper ausgerüsteten Membranele­ mente verkürzt. Zu einer Verkürzung der Lebensdauer trägt auch die Tatsache bei, daß das Drahtgitter korrodieren kann. Ferner ist bei dem bekannten Stützkörper infolge des zwischen die Platten eingelegten Drahtgeflechts die Gesamtdicke des Stützkörpers und damit des Membranelements verhältnismäßig hoch. Außerden ist wegen der verhältnis­ mäßig großen Anzahl von Bauteilen die Herstellung des bekannten Stützkörpers kompliziert und kostspielig.In the known support body is to form the Ab a wire mesh between the porous plates inserted so that the get through the membranes can flow out mixture component. As a result of the wire however, grids occur when a pressure gradient is created Bends due to folds or in the membranes Hairline cracks can occur. This will make it effective separation deteriorates and the lifespan of the equipped with a known supporting body diaphragm moments shortened. Contributes to a shortening of the lifespan also the fact that the wire mesh corrode can. Furthermore, as a result of the known support body of the wire mesh inserted between the plates Total thickness of the support body and thus the membrane element relatively high. Aussden is because of the relationship moderately large number of components the manufacture of the known support body complicated and expensive.

Der Erfindung liegt die Aufgabe zugrunde, einen Stütz­ körper für Membranelemente der gattungsgemäßen Art zu schaffen, der bei geringen Abmessungen und billiger Her­ stellung eine erhöhte Lebensdauer aufweist.The invention has for its object a support body for membrane elements of the generic type create the small size and cheaper Her position has an increased service life.

Diese Aufgabe wird erfindungsgemäß durch die im kenn­ zeichnenden Teil des Patentanspruchs 1 beschriebenen Maßnahmen gelöst. This object is achieved by the in the kenn Drawing part of claim 1 described Measures solved.  

Da bei dem erfindungsgemäßen Stützkörper die porösen Plat­ ten direkt aneinander anliegen, ergibt sich eine insgesamt steifere Konstruktion, so daß die Ausbildung von Falten und Haarrissen in den Membranen ausgeschlossen ist. Infol­ gedessen wird, auch wegen der fehlenden Korrosionsmöglich­ keit, die Lebensdauer des Stützkörpers und damit des Mem­ branelementes wesentlich erhöht. Dabei ist der erfindungs­ gemäße Stützkörper einfach und billig herstellbar und weist eine geringe Dicke auf. Dies führt dazu, daß in einer Vorrichtung zur Trennung von Gas- und Flüssigkeits­ gemischen bei gleichem Volumen mehr Membranelemente un­ tergebracht werden können, wodurch die Leistung einer solchen Vorrichtung gesteigert wird.Since in the support body according to the invention the porous plat If they are in direct contact with one another, the overall result is stiffer construction, so that the formation of wrinkles and hairline cracks in the membranes is excluded. Info is being eaten, also because of the lack of corrosion speed, the service life of the support body and thus of the mem significantly increased. Here is the fiction according support body easy and cheap to manufacture and has a small thickness. This leads to the fact that in a device for separating gas and liquid mix more membrane elements with the same volume can be brought up, which makes the performance of a such device is increased.

Eine bevorzugte Weiterbildung des erfindungsgemäßen Stütz­ körpers ist Gegenstand des Patentanspruchs 2.A preferred development of the support according to the invention body is the subject of claim 2.

Die Erfindung wird anhand der Zeichnung näher erläutert. Es zeigtThe invention is explained in more detail with reference to the drawing. It shows

Fig. 1 die Gesamtansicht eines mit dem erfindungsgemäßen Stützkörper versehenen Membranelementes und Fig. 1 shows the overall view of a membrane element provided with the support body according to the invention and

Fig. 2 eine aus Membranelementen aufgebaute Vorrichtung zum Trennen von Gas- und Flüssigkeitsgemischen. Fig. 2 is a membrane composed of elements apparatus for separating gas and liquid mixtures.

Das Membranelement 20 (Fig. 1) enthält zwei semipermeable Membranen 1, die beispielsweise aus Polyvinyltrimethylsilan ausgeführt sind, zwischen denen ein poröser Stützkörper einge­ schlossen ist. Der Stützkörper ist aus zwei po­ rösen Platten 2 aufgebaut, die auf der einen Seite flach, auf der anderen gerippt und mit den gerippten Seiten einander zuge­ wandt sind. Auf den flachen Seiten der Platten 2 sind die Membranen 1 angeordnet; infolge der Rippen auf den anderen Seiten entstehen zwischen den Platten 2 Kanäle zur Abführung des angereicherten Gemisches. Die semipermeablen Membranen 1 und der Stützkörper sind an der gesamten Umfangskante 3 des Elementes abgedichtet.The membrane element 20 ( Fig. 1) contains two semipermeable membranes 1 , which are for example made of polyvinyltrimethylsilane, between which a porous support body is closed. The support body is made up of two po porous plates 2 which are flat on one side, ribbed on the other and facing each other with the ribbed sides. The membranes 1 are arranged on the flat sides of the plates 2 ; As a result of the ribs on the other sides, 2 channels are created between the plates for discharging the enriched mixture. The semipermeable membranes 1 and the support body are sealed on the entire peripheral edge 3 of the element.

Das Membranelement 20 arbeitet folgendermaßen:The membrane element 20 works as follows:

Ein zu trennendes Gemisch (beispielsweise atmosphä­ rische Luft) wird der Oberfläche der semipermeablen Membra­ nen 1 des Elementes unter Druck zugeführt. Infolge der un­ terschiedlichen Durchdringungsfähigkeit von Sauerstoff und Stickstoff diffundiert durch die Membranen 1 vorwiegend die mit Sauerstoff angereicherte Luft, die dann durch die Poren der Platten 2 in die von den gerippten Seiten der Platten 2 des Elementes gebildeten Kanäle gelangt. In diesen Kanälen bewegt sich die angereicherte Luft zu einer Öffnung 4, aus welcher sie über den Sammler des Membranapparates als Fertig­ produkt abgeführt wird.A mixture to be separated (for example atmospheric air) is supplied to the surface of the semi-permeable membrane 1 of the element under pressure. As a result of the different permeability of oxygen and nitrogen, the oxygen-enriched air diffuses through the membranes 1 , which then passes through the pores of the plates 2 into the channels formed by the ribbed sides of the plates 2 of the element. In these channels, the enriched air moves to an opening 4 , from which it is removed as a finished product via the collector of the membrane apparatus.

Die von den gerippten Seiten der po­ rösen Platten 2 gebildeten Kanäle setzen den hydraulischen Widerstand beträchtlich herab und gestatten, die Luft mit Sauerstoff bis zu 42% bei minimaler Dicke des Membran­ elementes (0,7-0,2 mm) und hoher Packungsdichte der Mem­ bran im Apparat (bis 600 m2/m3 anzureichern. The channels formed by the ribbed sides of the po porous plates 2 considerably reduce the hydraulic resistance and allow the air to contain up to 42% oxygen with a minimal thickness of the membrane element (0.7-0.2 mm) and high packing density of the membrane bran in the apparatus (up to 600 m 2 / m 3 to be enriched.

Die in Fig. 2 gezeigte Vorrichtung zum Trennen von Gas- und Flüssig­ keitsgemischen enthält ein zylindrisches Gehäuse 5, einen Deckel 6, Stutzten 7 und 8 zur Einleitung bzw. Abführung des zu trennenden Gemisches, und ein Paket von Membranelementen 20, die aus den Membranen 1 und den porösen Stützkörpern 2 gemäß Fig. 1 ausgeführt sind.The device shown in FIG. 2 for separating gas and liquid mixtures contains a cylindrical housing 5 , a cover 6 , connecting pieces 7 and 8 for introducing or discharging the mixture to be separated, and a package of membrane elements 20 which are made from the membranes 1 and the porous support bodies 2 according to FIG. 1 are executed.

Jedes der Membranelemente 20 kann die Gestalt einer runden Scheibe mit abgeschnittenen Segmenten haben. Hierbei werden beim Zusammenbau dieser Membranelemente zu einem Paket die Scheiben relativ zueinander so angeordnet, daß die abge­ schnittenen Segmente derselben zu verschiedenen Seiten in bezug auf die Längsachse des Sammlers 9 zu liegen kommen, wodurch das aufeinanderfolgende Überströmen des anzureichern­ den Gemisches von einem Membranelement 20 zum anderen sicherge­ stellt wird.Each of the membrane elements 20 can have the shape of a round disk with cut off segments. Here, when assembling these membrane elements into a package, the disks are arranged relative to one another such that the cut segments thereof come to lie on different sides with respect to the longitudinal axis of the collector 9 , as a result of which the consecutive overflow of the mixture to be enriched by a membrane element 20 is ensured to others.

Die Membranelemente 20 sind auf dem Sammler 9 mit Dichtungsbeilagen 10 aufgereiht. Das Paket der Membranele­ mente mit den Beilagen ist von einer elastischen Hülle 11 umschlossen, die an den Stirnflächen 12 der Elemente und an einem Vorsprung 13 anliegt, der am Deckel 6 ausgebildet ist und dessen Umfang mit dem Unfang des Paketes der Membranele­ mente übereinstimmt. Als elastische Hülle 11 können die Polyäthy­ len-, Lavsan- oder ein anderer polymerer Film mit klebriger Schicht oder ohne diese, thermisch schrumpfbare Polymerfil­ me sowie gewebte Stoffe verwendet werden, die mit selbsthär­ tenden polymeren Massen, beispielsweise mit Epoxidharzen, imprägniert sind.The membrane elements 20 are lined up on the collector 9 with sealing inserts 10 . The package of the membrane elements with the inserts is enclosed by an elastic sleeve 11 which abuts the end faces 12 of the elements and a projection 13 which is formed on the cover 6 and the circumference of which corresponds to the extent of the package of the membrane elements. As an elastic sleeve 11 , the Polyäthy len-, Lavsan or another polymeric film with or without a sticky layer, thermally shrinkable polymer films and woven fabrics can be used, which are impregnated with self-curing polymeric compositions, for example with epoxy resins.
